} To all whom it may concern Be it known that we, Gnonea S. 'WITHAM and Isaac J. Wrrnaat, citizens of the United States, residing at Hudson Falls, New York, have invented certain new and useful Imlprovements in A paratus for Delivering and Trimming Pu p Articles, of which the following is a clear, full, and exact description.

This invention relates to an apparatus for .delivering and trimmin pulp articles, and may be used in connection with those machines for making articles of paper pulp which machines are provided with a mold 16 comprisin two sections to form the ulp article an from which mold the artic e is to be delivered and the ulp arts which may be attached to the e ge o the article trimmed of! or removed. I 20} One of the objects of the present invention is to deliver from such a machine, the

,pulp article to be trimmed.

E Another object is to provide means for ltrimming off or removing the clinging poritions at the edge of the formed ulp articles and for separating the trimmmgs from ithe pulp articles.

Other objects are'to provide simple and practical means for accomplishing the said pur ose.

T ese being among the objects of the present invention, (the same consists of certain features of construction and combinations of parts to be hereinafter described with reference to the accompanying drawings illustrating a suitable embodiment of the invention, and in which- Figure 1 is a plan-view of the improved apparatusshownin connection with a portion of a machine for 'makin articles from paper pulp; Fig. 2 is a side e ovation of the apparatus; Fi 8 is a section on the .line 13 3 Fig.2; i .4 is a section 'on the line Fig. 1; an Fig. 5 isa plan'of a pulp larticlew'ith theattached parts which, are to be removed. a

r Fig; 5*shows a plate'a made from paper pulpvvith the remainderoof the sheet of pulp, ,from"; which said plate has been formed, attached. A paper pulp plate is only cited as one instance of a pulp article which may be treated by the improved apparatus of the present invention. In the formation of the pulp article such as a plate, the attachment of the surrounding portion 6 which is to be removed is greater than at other times and frequently the degree of attachment varies. The machine for making the pulp article is intended to permanently define the outline of the ultimate article and means are provided under the present invention to break the attached portions away from the defined edge of the pulp article and to leave the edge in first class condition.

The drawings illustrate a portion of a machine for making articles of paper pulp, see Fi s. 1 and 4, and such machine may comprlse a turn table 1 and mold sections 2, 3, supported on such turn table and provided with suitable means of operation forming no art of the resent invention. Of course he machine is provided with means for opening up the sections of the mold so that the formed pulp article may be removed. An accessory to the present in vention and to said machine mriy be a blast nozzle 4 so located at one side of the sections of the mold as to enable a blast to blow the formed pulp article from between the open mold sections and to discharge thesame outwardly from the machine. The pulp article with the untrimmed edge portions is delivered from the machine for making the article, u on a belt convever 5 which is supported in a suitable manner as by end rollers 6, 7, and guide rollers 8, 9, from a frame 10. The said conveyor belt 5 is substantially horizontal although it may be inclined more or less and its upper lap runs between side walls 11, 12, arranged parallel with each other and supported on the frame 10, so that in substance the upper lap of the conveyor belt and the side walls 11, 12, constitute a trough with a traveling bottom.

At the receiving end of the conveyer belt 5, there ismounted u on the frame 10 a guard apron 13 which 1s suitably supported 1 by said frame in horizontal position and is intended ,to substantially 'fill the ga between" the receiving end. of the belt or trame andtheflmachine .-'1,-1'2',- 3. The said guard apron'"13"isintendedto prevent pulp art-i-' cles deliveredfrom the machine 1, 2, 3, from falling betwee'n: the latter and the frame or belt, "and to compel the pulp articles to be delivered on to 'i the conveyer belt. Opposite the blast nozzle or delivery device 4, there .is supported. above the frame 10 an interceptingfwalh 14 'atthe ofiside of the conveyer belt and 'saidwall ma be formed as a continuation of the side wa l 11 or may be a.separatewallilattached to the frame.

The upper lapof conveyer belt 5 travels in receive the ed es of the rings or annular rails-19, 20, w iich are fixed upon posrte ends ofthe said tumbling barrel. T c said turn the in 1t.

barrel ma be rotated as by belt 21 so as to barrel with the articles contained The said tumbling barrel 15 is of .i'rusto-conical shape, the smaller receiving end 15" being properly located relatively to the conveyor belt to permit said belt to o deliver the pulp .articles into the barrel. The pposite larger end of said barrel constitutes the discharge end for the trimmed pulp articles. In the drawings the said barirel is shown as inclined on its longitudinal axis and this facilitates the dischar e of the ;trimmed pulp articles. The tumb ing bar- 1 rel is rovidcd with a series of openings 22 ;andt ese. openings while com aratively lar e are not,.as large as the pa p article sue 1 as a, Fig. 5, after it has been trimmed.

Yet the openingsare ,of such size as that the edge portionssucli as b, F1 5, which E for delivering andtrimming are trimmed-off maylfallthroug i the openings. The tumblingbarrel is in the nature of a rotary screen with large openings.

- The operation ofthe described apparatus ulp articles lis as follows: Assoon, asa pu particlehas I; blast from the nozzle 4- immediately been roduced in-theunacliine such as 1, 2, 3 .an the mold sections havoc ened, (fire charges the article from the=machine on to the receivingend of; conveyertbelt 5. This belt isdriven in any ysuitable manner.- as

ishown in Fig. 2;- Theuntrimmed pulp articles such-as[a,.b, Fig. ti, are delivered one at a timefintothe, tumbhng'barrel.15Zand as this barrel" rotates, t: the pulp articles are shakeniand' tumbled about ,within the barrel until ultimately all of the portions such 6' from the outlet end 15 of the tumbling barrel.

What we claim as new is: 1 1. In apparatus for delivering and trimminfi pulp articles, the combination with a mac me ior makin pulp articles, of a conveycr, means for de ivering the pulp articles from said machine onto said conveyor, and means for removing the ulp portions attached to the ed es of said articles and to which means sai conveyer leads.

2. In apparatus for delivering and trimmin pulp articles, the combination with a mac iine for making pulp articles, of a conveyer, means for delivering the pulp articles from said machine onto said conveyer, and a tumbling barrel, to which said conveyor conducts said articles, for removin Y the pulp portions attached to the edges 0t said articles.

3. In apparatus for delivering and trimmin pulp articles, the combination with a mac iine tor makin pulp articles, of a conveyer, means for delivering the pulp articles from said machine onto said conveyer, a guard-apron between said machine and conveyer, and means for removing the pulp portions attached to the ed es of said articles and to which means sai conveyer leads.

4. In apparatus for delivering and trimmin pul articles, the combination with a mac ine or makin pulp articles, of a conveyer, means for do ivering the pulp articles from said machine-onto said conveyor, an intercepting wall above the far side of said conveyer to compel the pulp articles to fall onto said conveyer, and means for removin the pulp ortions attached to the ed cs 0? said artic es and to which means sai conveyer leads.

5. In apparatus for delivering and trimmmfipul articles, the combination with a mac me or makin pulp articles, of a conveyer, means for de ivering the pulp articles from said machine onto said conveyor, and an inclined frusto-conical tumbling barrel having its smaller receiving end presented to the discharge end of said conveyer.

6. In apparatus for delivering and trimmin pul articles, the combination with a mac une 'or makin pulp articles, of a conveyer, means for de ivering the pulp articles fro'ni said 'm'agiliixi onto said conveyer,and Signed at Hudson Falls, N.
